Question

you move down 4 units. you end at (-1, 0). where did you start?

Explanation:

Step1: Understand vertical movement

Moving down 4 units means subtracting 4 from the y - coordinate. Let the starting point be $(x,y)$. The ending point is $(-1,0)$. Since we moved down 4 units to get to the y - coordinate of 0, we work backwards.

Step2: Calculate the starting y - coordinate

We know that $y-4 = 0$. Solving for $y$ gives $y=4$. The x - coordinate does not change during vertical movement, so $x=-1$.

Answer:

$(-1,4)$
